GASKET. Application filed August 12, 1927. Serial No. 212,596.

My invention relates to gaskets and pardiameter as the perforations and flat rear 65 ticularly to gaskets having projecting porfaces 16. tions by which they are secured to a support- In order to be able to force the heads of ing member. An object of my inventionis the projections easily and quickly through the provision of .an improved gasket whose the perforations, I form the gasket with the construction facilitates the'ease and rapidity opening 8 at eachprojection 3 which open- 60 with which it may be applied to the supporting extends from the-front face of the gasket ing member. through the body portion thereof and through My invention will be-gbctter understood the neck into the head where it terminates.

The gasket preferably is con.- tion and it.will be apparent that various structed of a resilient material such as rubmodifications may be made without departher and the spacing ofthe projections thereon mg from the spirit and scope of my imam-. preferably is slightly less thanv the spacing tion which modificationsI aim to cover by porting member whereby the resulting slight What I claim as new and desire to secure 5 stretching of the gasket assists in making by Letters Patent of theUnited States is:

it lie flat and trim. The projections are shown 1. A gasket adapted to be applied to a memeachhavin a conical head 6the base of which ber having a perforation therein, said gasket Iy-larger in diameter than the perhaving a portion larger than the perforation forations, a. neck 7 of substantially the same and adapted to be reoeived thereby and hav- Y in" an. openin extending incompletely th rough said 'p rtion whereby the gasket the member.

may be applied to the member by inserting a member inthe opening in the gasket and forcing said portion into the perforation in 2. A gasket adapted to be'applied to a memher having a perforation therein, said gasket having a body portion and'a securing portion, said securing portion being larger than said perforation, said gasket having an opening extending through said body portion and partiallythrough said securing portion whereby said securing portion is adapted to be forced through said perforation by a member inserted in said opening. I

3. & gasket adapted to be applied to a member having a perforation'therein, said gasket having a body portion and having an inte- -gral head portion larger than the perforation and adapted to be passed therethrough, said gasket having an opening extending through the body portion entit -terminating in the head portion, whereby the head portion may be forced through the perforation in the mem' her by a member inserted in said opening and the gasket thereby secured to the member.

4. A gasket-adapted to be applied to a member having a series of=-perforations therein,

said gasket comprising a strip having a se rles of prqectmg portlons Larger than and perforations for securing the gasket to "the member, said strip having openings there through, each extending into and terminating in a projecting position.

5. A gasket adapted to be applied to a memher having a series of perforations therein, said gasket comprismga strlp havlng a. se

- necting neck, said strip having an opening portions extending through 4:5

ries of securing portions projecting from one side thereof, each of said portions comprisinga-head of greater diameter than that of the "perforations in said member and a 0011- for each of said the strip and the neck and terminating in the head. i

6. K gasket adapted to be applied to a member having a series of spaced perforations therein, said gasket comprising a strip having a series of securing. portions pro ect1ng from one side thereof and spaced less than said perforations," each of said portions comp'rismga conical head having a diameter at the base greater than the diameter of said perforationsand a neck connecting the head with the strip,

said strip having anopening for each of said portions extending through the strip and the I neck and'terminating within the head.

7. The herein described method of making a tight seal byattaching rubber articles to plates of non-elastic material which con-.

9. The herein described method of making a-tight seal b attaching rubber gaskets to sheet metal w iichconsists in providing such sheet metal with a plurality of openings, securing to the surface of the gasket :1; plurality of headed attaching part-s spaced apart a distance approximating the distance between the holes, and inserting the attaching members through the holes. p

10. The herein described method of making a tight seal by attaching rubber gaskets to a sheet metal carrying plate which consists in providing said plate with a plurality of holes, providing a deformable gasket ineluding a gasket strip part-and integral attaching parts, and inserting the attaching parts in said holes by deformation of one or more of said parts.

11. In combination, a carrying plate having spaced apart holes, and a rubber gasket having integral rubber attaching means adapted to pass through said holes and having heads with flat rear faces and 9, connecting neck, said flat rear faces adapted to .en-

- gage the rear face of said plate.

12. A refrigerator, a closure therefor, a rubber gasket on one member of said closure having unitary headed attaching projections withflat rear faces and-a connecting neck.

In witness whereof, I have hereunto set my hand this 11th day of August, 1927. p
